Great budget lift kit
Installed on a 2022 Nissan Frontier Pro-4X with the stock Bilstein 4600s.
The lift is noticeable while driving but feels good, a little stiffer than stock but I found stock was a little bouncy and that is now gone. I am happy with how it rides.
I am a mechanic, so for me install was easy, 5 hours, about 20 minutes to do the alignment. I would recommend camber bolts as I had to adjust my camber and caster, which are not factory adjustable.
The truck looks a lot better at this height which is definitely noticeable from the exterior.

I definitely recommend this kit to anyone who wants to lift their truck a couple inches without have to replace upper control arms.

Installs and Works as Expected
Installed on a 2023 Nissan Frontier Pro-4x with the factory Bilstein shocks.

The lift is noticeable while driving (in a good way), but it’s readily noticeable from the outside, unless you’re familiar with how the factory height looks.

Everything else on the truck is stock for now.

My friend and I were able to install this in about a day. The only trouble we ran into was installing the coil overs… we ultimately needed to rent a heavy duty coil over press, but in retrospect, I would have brought the shocks to a shop and paid them to replace/install the coil overs.

I’d recommend buying/install the Adjustable Cam Bolts as well.

Overall, I think it’s a great kit that adds some functionality (relative to a spacer kit at least), that wasn’t too expensive and relatively easy to install.

I would highly recommend if you’ve got a new truck and just want to leverage the existing shocks.

2022 Pro4X
Lift looks awesome.  A little firmer than stock but in a good way.  The stock suspension was too bouncy.  I definitely recommend getting the 1/2" spacer and the LCA bolts are a must.  I have not experienced any CBC and I have been offroad since the lift was installed.

ADO 2 inch front coil speings
Got my ADO front springs installed today. The truck rides great and so far no issues. I have a 23 pro4x and they made my truck look perfect.

Solid And Fully Functioning Lift Kit
I did an extensive research on what the different kinds of lift kits available for the Frontier, and saw much of them as spacers, which if if used without an aftermarket UCA will have clearance issues, aka CBC. Then I saw ADO videos in YT explaining the logic and all makes perfect sense. I now have these kits on my truck and glad I did!

2022 Frontier Pro 4X
Definitely happy with the end result. Rides great, firmer than stock for sure. Couple notes I'd pass along, especially if you're installing on a '22 or newer... new U-Bolts were too wide to fit into the mounting brackets, we had to put them into a vice and make them a bit more narrow. This is in addition to having to drill out the holes in the brackets to 9/16". There is also a rear sway bar on the current gen's that you'll need to disconnect for install. Lastly, really wish ADO wouldn't paint their hardware for the AAL's. Makes for a huge mess and some challenges in re-assembly.

Again, all in all, very happy with the look and ride. Definitely doable DIY install without a lift but we found having two jacks helpful in the rear. One for the truck and one for raising/lowering the diff.

Rides great!
Have had this kit on for a few weeks now. Rides great, looks great. Clears 285/70r17 tires. Small note: still maintains factory rake.

Good Kit But….
If you are looking for 2” of lift without spending a ton of money this is the kit for you. Beware the U bolts rust. I just changed to a different set of springs and had to cut the bolts off because they had rusted so bad. I don’t live in the rust belt and it’s only been 18 months. My impact gun wouldn’t even spin the nuts.

2022 Nissan Frontier ProX
I put this kit on a couple of months ago, and I have to say it rides GREAT! Personally, I think it's better than stock, especially over large bumps.

My only complaint with the kit was not knowing they used bigger U-Bolts, so I had to make a trip to buy a drill bit to drill out the plates to 9/16's.

Other than that they ride very very well.

2013 Frontier SL 4x4
I installed this kit with a set of Bilstein 4600's.  I did not reinstall the overload leaf in the rear. I haul fairly often and I have had no problems with excessive sag. The ride quality is MUCH better.  

My only issue was the U-bolts.  They would not fit through the factory plate and needed to be drilled out to 9/16th.   I did not have that size bit on hand and had to re-use the factory bolts for a day.  I feel like that should have been in the product notes.

I would recommend new strut mounts and a hydraulic spring compressor to anyone doing this at home.

Great kit!
Perfect kit if you've got a PRO4X with the Billstein 4600 shocks still in great shape. They're perfectly good performance shocks still and this kit complements them perfectly. Gets rid of the stock rake, nice aggressive lift with the piece of mind of not using spacers. Very pleased with my RC Killa kit.

2020 Nissan Frontier King Cab 4x4 Long Bed
Had the pleasure speaking with Chad via email. Gave awesome advices on what I wanted. Nothing too drastic, just wanted a lift to clear me for 33” tires. This kit is perfect. I didn’t need to replace my 4600 series Bilstein, but did it anyway and they pair up very well with the lift kit. The ride is awesome and surprisingly smooth. Thank you gents!! Cheers!!

Perfect kit for my 2020 Pro4X
I followed the advice of the guys at ADO and went with this spring kit since my stock Bilstein 4600s only have a few miles on them.  Also added the cam bolts for alignment. Ride quality of suspension is much better than stock and the height adjustment is perfect. Enough to improve ground clearance and make the truck look great. Not too much to create other problems that spacers or taller lifts can produce. Stayed with 16” factory wheels and 265/75 r16 BFG ATs. Again, perfect match for this kit. My guess is that bigger tires and wheels would fit with minor trim adjustment.

This is it!
This is a FANTASTIC kit. My 2012 Pro4x still rides smooth and handles well. It gave me roughly 2" lift on the front and roughly 1.5" of lift in the rear.

I also paired this with Bilstein 5100's. Works fine with 4600's as well though, but the 5100's will allow for greater suspension travel to keep the wheels planted when off-roading.

Order those camber bolts with it!

Great Kit!
I've had this kit for little while and all I can say is that its a great lift kit! The ride is much better (on and off road) than any spacer kit and it was a very easy install. If you do any off roading at all and are looking for a good kit at a great price, this is the one!
